Frequently Asked Questions
How do I convert IST to EST?
Select India Standard Time as the from zone and New York as the to zone. IST (UTC+5:30) minus EST (UTC−5) means New York is 10 hours 30 minutes behind — 10:00 AM IST is 11:30 PM the previous day in New York.
What is the time difference between India and the UK?
London is 5 hours 30 minutes behind India. 12:00 noon IST is 6:30 AM in London.
Why might the conversion be off by an hour?
The converter uses standard time. Cities with daylight saving time — like London, New York, Berlin and Sydney — shift by one hour during their DST periods (typically April–October).
What is UTC?
UTC (Coordinated Universal Time) is the global time standard that all time zones are measured against. IST is UTC+5:30, meaning India is five and a half hours ahead of it.
